What Is Glycol Used For In Hvac?

What Is Glycol Used For In Hvac?

Have you ever wondered what makes your HVAC system run so smoothly and efficiently? One of the key components that plays a crucial role in ensuring the optimal performance of your air conditioning or refrigeration system is glycol. Despite being a relatively lesser-known substance, glycol has been widely used in HVAC systems for decades due to its unique properties and benefits. In this blog post, we will explore what glycol is and how it can help improve the functionality, safety, and longevity of your HVAC equipment. So buckle up as we take you on an informative journey into the world of glycol!

What is Glycol and What Does It Do in Hvac?

Glycol is a versatile and popular chemical used in many industries including hvac. It is primarily used as a coolant and solvent in air conditioning, refrigeration, heating and ventilation systems. Glycol is also effective at preventing corrosion and preventing moisture from reaching equipment.

Uses for Glycol in Hvac Systems

Glycol is a common name for a type of alcohol that has been used in the past as a coolingant, antifreeze, and engine fuel. Today, glycol is most commonly used in air conditioning and heating systems because it evaporates slowly and does not form toxic byproducts when it’s burned.

Glycol is often used to maintain refrigerant levels in HVAC systems. When the glycol evaporates from a cooling system it takes away heat from the indoor air. Glycol also helps to prevent freezing on cold winter days.

The glycol in HVAC systems can also help to reduce emissions by breaking down smog causing compounds into shorter molecules that are easier to break down by the atmosphere.

Risks of Glycol Use in Hvac Systems

There are many risks associated with the use of glycol in HVAC systems. Glycol is a flammable and toxic substance that can easily cause fires in air conditioning and heating systems. It can also damage equipment and cause leaks that can contaminate the indoor environment. In extreme cases, glycol-contaminated air can lead to serious health problems.


Glycol is a valuable chemical used in HVAC systems. It’s responsible for cooling and heating buildings, and it has a number of purposes within the HVAC system. Glycol helps to create humidity in the air, which is necessary for proper system operation; it also helps to prevent ice from forming on coils and other mechanical parts. In addition, glycol can help reduce noise levels in an HVAC system. So if you’re looking to improve your building’s comfort or reduce noise pollution, understand the role glycol plays and consider using it in your next project.
